Merging module 304 may update the master text transcript as transmission module 302 stores updated local device text transcripts in local device text transcript data 310 of database 124. In an embodiment, merging module 304 may update the master text transcript substantially in real time; in other embodiments, merging module 304 may update the master text transcript once every second, once every five seconds, or at any other frequency.

According to embodiments, merging module 304 uses one or more consensus mechanisms to rectify discrepancies between the local device text transcripts and to merge the local device text transcripts into a single master text transcript. For example, in an embodiment, merging module 304 may utilize a majority consensus mechanism to merge the local device text transcripts into a single master text transcript. In this example, merging module 304 implementing the majority consensus mechanism preferentially chooses dialogue text present in the majority of local device text transcripts over dialogue text present in only a minority of local device text transcripts. To provide a more specific example of merging module 304 using a majority consensus mechanism, in an embodiment in which merging module 304 accesses three other local device text transcripts stored in local device text transcript data 310, and two of these local device text transcripts contain the sentence “I tied the knot” at a particular chronological point in the transcript whereas the third local device text transcript contains the sentence “I tied the not,” at the same chronological point in the transcript, merging module 304 selects “I tied the knot” and not “I tied the not” to include in the master text transcript. Although particular consensus mechanisms are described herein, embodiments contemplate merging module 304 utilizing any consensus mechanism to rectify inconsistencies in the plurality of local device text transcripts, according to particular needs.

According to embodiments, and having generated the master text transcript, merging module 304 stores the master text transcript in master text transcript data 312 of cloud system 120 database 124. Merging module 304 may store the master text transcript as a plain text file, an encrypted file, or in any other format capable of storing a text file.

According to embodiments, transmission module 302 accesses the master text transcript stored in master text transcript data 312. Transmission module 302 transmits the master text transcript to the administration modules 202 of each of two or more communication devices 110 participating in the teleconference space using network 130 and communication links 140-142. Each communication device 110 administration module 202 stores the master text transcript in master text transcript data 220 of communication device 110 memory 114. In an embodiment, transmission module 302 may transmit the master text transcript to each of other communication devices 110 substantially in real time; in other embodiments, transmission module 302 may transmit the master text transcript to each of other communication devices 110 once every second, once every five seconds, or at any other frequency.
